The Kindle iPad app has many nice features, but one a that most people don’t know about is the ability to look at annotations made by other people.
By switching on this option, whenever you’re reading a book every so often pieces of text will appear underlined – these are pieces of text underlined by several other buyers of the same book.
To turn this on, open the information box, then open “settings”, and then turn on “popular highlights”. You can turn it off at any time.
